SVG Icon Builder: Now Available in the Microsoft Store

The SVG Icon Builder is documented here. It provides
template shapes that you can mix to create custom icons. The tool is highly useful both for developers struggling with free-hand icon drawing, and for
designers to create glyphs that fully support the icon colorization feature.

You can add up to 4 different small action images to a primary icon, rotate
and flip every glyph, and set individual colors for each icon element. Final
icons can be saved as both vector SVG and raster PNG files.
